Abstract:
A method of controlling access to an elevator car, in particular to its roof and/or underside, including the steps of switching the elevator control into a maintenance mode which controls the car to travel to a predetermined stop position permitting access, and opening a landing door of the elevator shaft the car is running in. The elevator control is switched into the maintenance mode only if operating a landing call receiving device in a predetermined identification pattern which differs from a call pattern for calling the elevator.
